Title: Notifier config improvements: db dir, email vars

- specify notifier_db_dir as a setting. Had previously just stuck
under $HOME, but Jim preferred as a distinct setting.

- pass through email settings env variables

- plumb through django's EMAIL_USE_TLS setting. Required to be
able to send mail using Amazon SES. They speak smtp, but only
over TLS.

Pls review @e0d.
